This invention relates to improvements in methods of and means for use in locating shank pieces of the type wherein an aperture is provided for the reception of a heel-attaching screw. a

In United States Letters,Patent No. 1,615,258,'granted Jan.r25, 1927 upon ap plication of M. V. Bresnahan, there is disclosed a method of attaching heels- Which involves the use of a last having a holeor perforation extending through its rear; portionfromthe top of the cone to the bottom of the heel seat and which comprises the following steps or operations, viz., assembling an upper and an insole on the last, pulling-over and lasting the upper and securing it to the insole, laying -an outsole, positioninga heel upon the shoe, and passing a drill through the hole in the last and operating it to bore holes through the soles and into the heel in line with the hole in the last in preparation for the insertion through the last and into the heel of a screw -fastener for temporarily clamping together the last, the shoe and the heel and for the subsequent insertion of a wood screw from the inside of the shoe for permanently securing the heel to the shoe. In acopencling application, Serial No. 419,666, filed Jan. 9, 1930, in the name of F, C.

'Ayling, the above-described method of heel attaching is disclosed as being practised in connection with the manufacture ofshoes of the type wherein a. shank stiffener extends rearwardly toa point located above the heel, and a permanent heel-attaching screw extends through, and fits snugly within, a circular aperture invthe rear portion of the shankstifl'ener so as to providea rigid connection between the stiffener and the heel as well as to secure the heel to the shoe.- In the method disclosed in the Ayling application justreferred to, the method of attaching heels disclosed in the above-mentioned Letters Patent No. 1,615,258 is further modified to the following extent, viz.,

before the shank piece is applied-to the shoe a heel-fastener-receiving aperture is formed in the insole by-means ofa drill passed through the hole in the last, and thereafter the fastener-receiving aperture in the shank stiffener is located relatively to the hole in the insole by means of a taperedv wooden peg which is driven through the aperture in the stiffener and into the holes in the insole and the last' and later, during theoperation of.

drilling a hole-in the heel, the drill operates also to drill outthe wooden peg andi'thus to reopen the hole previously formed in the insole as wellastodrillthrough the outsole and into therheel.

V One object of thepresent invention is;to

secure the various advantages of the method of shoe making disclosed in the Aylingi application above-referred to while making it still easier to locate a shank stiffener with its aperture suitably positioned for the passage, of adrill and-a heel-attaching fastener therethrough. a j .7. p 5 With this object in" View, the invention contemplates an improved, method of mak-, ing shoes which, considereduin one aspect,

comprises forming an integral locating projection ona shoe sole, and locating. an aperf- V fsole bypositioning the reinforcing member with the pro ection on the sole extending into'the aperture in the reinforcing member,

tured reinforcing member relatively to the Thereafter, as illustrated, the reinforcing member is secured; in itswlocatedposition and a hole is made in the solejin line with the aperture in the: reenforcing iimember,

thereby removing the locating projection and preparing the sole fora-the reception" of a fastener which isto-jext end alsothrough the aperture in the reinforcing member} As herein exemplified, in connection with themanufactureof a-shoe upon alast have by? means i of an elongated v spindle, having a free extremity whichishshapedto constitute a forming or molding member and which is passed. through the hole: in the last into-engagement with the inner side of the insole and is forced into the insole material Accordingly, it i'sgtof be recogwingta hole extending.fromethetop to the I bottom of its heel portiomthe locating projB CtlOIL lS formed in ani insole on. -the last step in the art of making shoes which comprises operating from the inside of a shoe on a perforated last to form a projection on the outer side of the insole of the shoe, for use in locating an apertured reinforcing member such as a shank-stiffener with the aperture in the reinforcing member in line with the perforation in the last. As

herein illustrated,the projection-forming extremity of the spindle co-operates with a complemental forming member in engagement with the outer side of the insolein forming the projection, the complemental member serving to support the insole against the thrust of the spindle.

After the reinforcing member or shank stiffener has been located by means of the projection and has been secured in place upon theinsole andin accordance with'the improved method as herein exemplified,the locating projection is cut away and a-heelfastener-receiving hole is formed in the insole in line with the fastener-receiving aperture in the shank stiffener by means of a drill-which is operatedthrough the holein the last. Thus both thehole inthe insole and the aperture in the stiffener are accurately located in-line with the hole or perforation infthe last andin position to receive a. heel-attaching fastener. The outsole-of the shoe may be laid before the drilling of the insole or, if desired, both the outsole may be laid and the heel attached to the shoe before the drilling operation is performed. Thus the drill may be employed to' form :ata single operation a hole through the outsole andin the heel as well as a'hole in the insole, and each of the holes so formedwill be aligned withthe'aperture in the shank erence to the accompanying drawing, in 7 l p i I "formlng couple 15 formed wlth a stem 16 piece and with the hole in the last preparatory to receiving a heel fastener-which will pass also through the hole ,inthe shank stiffener and will thus co-o'perate'with the shank stiffener to stiffen the shank and brace the heel as well to serve j as a permanent means for attaching the heel to the shoe.

Considered in anotheraspect invention is to be recognized as residing innovel apparatus for use in carryingout'the -above-described method, the illustrated apparatus comprising complemental forming members one'fof which is constructedand arranged to engage the outer face of a sole mounted upon a perforated last to support the sole and the last, and the other of which is constructed and arranged to extendthrough a perforation in the last and'toco'operate with the first member'to form a locating projection in the outer-face of the sole; i The invention will befexplained' wlth ref- .which v V N Fig. 1 is a View partially 1n side'elevation "and partially in; sect-ion of a projectionforming device adapted-to be usedi n carrying out the present method, the apparatus being shown in operation upon the insole of a shoe mounted on a perforated last;

Fig. 4.-'is a perspective view of a shoe as it appears after. the shank piece has been ,-the shoe.

The improved method of locating perforated shank pieces is herein illustrated as beingpractised in connection with the manufacture of'a'a shoe on a perforated last such as the last disclosed in the above-mentioned Bresnahan patent. As shown in the drawing, a last A of the type referred to is provided with a hole- 13 which extends through the heel portion of the last from the top of the cone to the bottom of the heel seat surface. After a shoe upper C and an insole D have been assembled upon the last A and the upper has been pulledover and lasted to the insole in a customary manner, as shown'in Fig. 1, a shank piece locating projection Eis formed on the outer side of the insole in line with the'hole B in the. last by 'mea ns' of the apparatus shown in Figs. 'lfa'nd 2,-su'ch apparatus comprising a spindle 10 adapted to be passed downwardly through the hole B in the last and to operate from the inside of the shoe to form the projection E. In the illustrated apparatus the spindle 10 is of a diameter adapted to pass freely through-the hole B in the last and to he guided by the latter so asaccurately to determinethe location of "the projection-on the insole. As shown, the

spindle 10 is provided with a reduced lower extremity 12 shaped to c0-0perate with a lower member 14L in forming the projection E, the'redueed extremity 12 and'the member 14; constituting respectively the upper which is received in the upper portion of a bore a block- 20 which in turn is 130 secured-by means 'of a set screw 22".within the recess, in a table 24 which surmounts a pedestal 26. A thumb screw 28 is threaded in the bore. 18 beneath the lower couple mem ber 14 for supporting the latter and adapting it for up and down adjustment according to the thickness of the insole to be operated upon to" adapt it to co-operate efi'ectively with theextremitygof the spindle 10 in forming the projec'tioninthe insole.

The spindlelO which carries the upper member 12 of the projection-forming couple is secured at its upper 'end by means. of a setscrew 30 to a cylindrical block 32 which is slidably mounted within atubular guideway. 34, thelatter being rigidlysupported between frame members 35 which extend upwardly from the table 24, and carrying at its lower end a bushing '36 through which the spindle lOis adapted to slide. The slid ing block 32 whichicarries the spindle 10 is adapted to be moved up and down within the tubular guideway 84 by 'means of toggle mechanism comprising'a link 38, the lower end of which is pivoted at 40 to the slide block 32 andv a link 42which is connected by a fixed pivot 14. with the upper end of the-guideway 3d and which is pivotally connected at 4:6 with the link 38. For operating the toggle links-38, 42 a rearwardly extending arm 48 on the link 42 is pivotally connected at 50 to the upper end of a rod 52, the lower end of which is adapted to be connected with a foot 'treadle (not shown) by means of which the rod 52 may be lowered for the purpose of straightening the toggle and forcing the spindle 10 downwardly through the hole in the last into a position for causing the couple members 12' and 14 to co-operate in the formation of the project-ion E' in theinsole. A spring 54 connected at its upper endwith the frame members36 and at itslower .end with-the treadle rod 52 is provided forbreaking the toggle. j 1 i In using the above-described apparatus, a perforated last of the type hereinbefore referred to, having a shoe upper and an insoleassembled thereon, (is placedin posi tion to be operated upon by introducing its heel portion between the upper and lower projectionforming members and 14, the last-being held by the operator substantially in the position in which it appears in Fig.

1,'and the spindle 10 which carries the upr per forming member 12 being'at this time in the raised or inoperative position shown in Fig. 2. The -operator then depresses the treadle connected with the rod 52 thereby operating the toggle links 42,38 to lower the spindle 10 until the upper formingmem- .ber 12.at the lower extremity of the-spindle enters the hole B in'ithe'last Continued depressionv of .the treadle moves 7 the. jspindle .10 downwardlythrough the .hole i'nithe last and finally causes the upper forming. memher 12 to engage l the insole and; -c o.' -'operate with-the-cavity in the lower ,forming' member 14.,toff0rn1.thezplojection E in the insolo... As shown,; the spindle? 10,- while it is adapted to passfreelythrough the hole in the last nevertheless substantially :fills that hole 'sothat no: play is permitted within the hole. Gonsequently, the projection formed inthe insole will be located in accurate ali'n'ement with the hole in the last-.- The mold. members 12 and 14 are shaped so that the; projection will present a smooth 'rounded'contour adaptedreadily to enter 1 ua1 longitudinal curvature I corresponding to the longitudinal curvature of thelast bottom and a hole or aperture is formedinthe rear portion'of the shank piece, the hole being arranged to register with a corresponding.

hole in'the rear portion of the filler piece shank 7 piece; 0i, a type G so that a.heel-fastened-receivingholeI is I formed which extends through both'the strip F and the filler piece G, "For use in shoes other than weltshoes it may be desirable to employa. shank piece consistingmerely of a metallic stripsuch as the strip F, the strip having a heel-fastener-17eceiv-ing aperture in its rear portion but having no. filler piece associated therewith. v 7

In assembling the shank piece with the shoe,-the shank fpiece is laid, upon the outer face of' the insoleD in such a position that 'theprojection' which has beenformed in the insole will, extend throughtheheel-fastener receiving hole in the shank piece thereby accuratelyilocating. the shank; piece .with' the hole: in alinementwith the hole B in the last. Thefshankpie'ceisthollfixedly secured in place on the shoe bottom, for example by means offtaoks .whichlmay be driven through. the filler piece, and into I the insole..'

The projection. E; having performed 1 its function? of locating 3 the. shank piece, is in accordance with: the, present method, removed, either before or after the heel isyattached to; the; shoe. .As; shown in .Fig figthe projection. Ejmay be removed before attachment of thehe'el by .means of a drillL which is passed downwardlyj thro'ughthe-i hole B in the last and which: isroperated to cut away" the projection E therebyaforming a hole through the insole in line-with :the hole in the last. 1 In Fig. .6, :the outsole is shown as i so having been laid prior to the performance of the above-described drilling operation and the drill operating to form a hole in the outsole M as well as in the insole.- If a heel is attached before any drilling operationis performed the drill maybe utilized to form, at a single operation, fastener receiving holes in both soles and in the heel, in addition to removing the locating projection on the insole. Inasmuch as'the drill is guided by'the hole in the last and inasmuch as the hole in the metalstiffener strip F has previously been located inaccurate :registration with the hole in the last the drill will not engage the metal in the stiifener strip and consequently there is no danger of breaking the'drill. After a hole has been drilled in the heel and the last has been pulled a permanentheel-fastener'in the form of awood screw may be insertedfrom the inside of the shoe,- the screw passing throughthe holesin the insole, the shank-piece, and the outsole and being screwed into the heel. There 1s, of course, no danger that the threads will be stripped from the screw by engagement withthe metal of the shank stiffener inasmuch as the hole in the latter has already been positioned in accurate registration with the holes inthe inner and outer soles and ing the heel.
